The early stages of the war in Iran already illustrate the familiar economic pattern of modern imperial conflict: immense state expenditures and growing national debt, alongside private corporate gains. The U.S. government spent about $5.6 billion on munitions in the first two days of strikes alone, and administration officials estimate the war cost over $11 billion in its first six days, with Congress preparing potential supplemental funding requests approaching $50 billion to sustain operations and rebuild military inventories just a week later. One month in and the Pentagon is also preparing plans for a request of $200 billion to sustain operations in the region. Such wars generate windfalls for energy and defense corporations while enlarging the state’s deficits and borrowing. Yet the state cannot infinitely borrow without growing the risk of a catastrophic economic crisis. The dynamic is not new. The financial crisis of 2008 exposed the contradiction between the massive destructive expenditures of imperial war and the declining capacity of the economy to sustain them. For years the American bourgeoisie had financed the occupation of Iraq through debt while presenting the conflict as a defense of national security. But when the financial system itself entered a crisis with banks collapsing, credit freezing, and millions losing their jobs and homes, the cost of the war appeared in a different light, and support for continued military campaigns among the bourgeois eroded.

Contemporary wars rely on extremely expensive and complex systems—precision-guided munitions, advanced aircraft, drones, and satellite-supported targeting—that are consumed far more quickly in sustained combat than they can be replaced. In the war in Ukraine, for example, the United States was reportedly producing only about 14,000 155mm artillery shells per month before 2022, while Ukrainian forces at times fired 6,000-8,000 shells per day, forcing emergency efforts to expand production toward 70,000–100,000 per month—a process expected to take years. Similarly, stocks of advanced weapons such as Javelin anti-tank missiles and Stinger air-defense systems were significantly depleted, with production lines having to be restarted or expanded after years of limited output. U.S. defense officials have acknowledged that current “consumption rates… are far beyond what most defense industries were prepared to supply,” highlighting the mismatch between peacetime production capacity and wartime demand.

At the same time, the cost and complexity of modern systems significantly slow their replacement: advanced missiles can cost hundreds of thousands to several million dollars each, while platforms like the F-35 Lightning II require long production timelines and highly specialized supply chains, leading analysts from institutions such as the Center for Strategic and International Studies and RAND Corporation to warn that rebuilding stockpiles of precision munitions could take several years even with expanded funding.

Historically, when technologically advanced arsenals are exhausted or constrained, warfare has tended to revert toward more labor-intensive forms, relying on larger numbers of troops to sustain operations. In this sense, the very capital-intensive character of modern militaries contains a limit: as the cost and scarcity of advanced systems collide with the demands of prolonged war, states may be forced back toward mobilizing proletarian soldiers on a larger scale. The implication is that beneath the surface of high-tech warfare, the underlying social reality reasserts itself, the potential reappearance of mass armies, bringing the ruling class once again into direct confrontation with an armed proletarian force. While the war in Iran has so far not seen mass deployments of U.S. troops like happened in Iraq, Karoline Levitt claims Trump refuses to take a draft of Americans for the war “off the table”. While a mass land invasion of Iran is unlikely it is not impossible and will in fact likely be necessary if the U.S. finds itself wrapped up in a long term conventional war.

Warfare today is far more capital-intensive than in the past, as seen in the contrast with World War II, when the United States produced over 300,000 aircraft and tens of thousands of tanks at relatively low unit costs,such as the B-24 bomber at about $300,000 (≈$5–6 million today),whereas modern systems involve dramatically higher costs, with an F-35 priced at $80-100 million, aircraft carriers exceeding $13 billion, precision-guided missiles costing $1-4 million per use, and recent wars in Iraq and Afghanistan reaching $2-3 million per soldier per year. As Friedrich Engels observed, “nothing is more dependent on economic conditions than precisely the army and navy,” and in this case the highly financialized, debt-laden, and speculative character of the U.S. economy is reflected in a military that is extraordinarily expensive, technologically advanced, and dependent on continuous flows of capital. Such a force, while immensely destructive, is also structurally burdened by the same contradictions as the economy that produces it, suggesting that when confronted with deeper social crises and potential mass opposition, it carries within it the limits and instabilities of the system it defends

The connection between war spending, economic crisis, and social upheaval amid mass conscription has historical precedence. The Vietnam War contributed significantly to the fiscal and monetary instability of the late 1960s as military expenditures surged while taxation lagged behind, fueling inflation and helping destabilize the international monetary system before the collapse of the Bretton Woods order in 1971. In earlier centuries similar pressures contributed towards revolutionary crises. The enormous debts accumulated by the French monarchy during the Seven Years’ War and the American War of Independence crippled state finances and helped provoke the upheavals of 1789. Most dramatically, the Russian Revolution of 1917 emerged from the catastrophe of the First World War, when military spending, economic breakdown, and mass casualties shattered the tsarist regime and radicalized workers and soldiers alike.

Mass warfare initially disciplines society under the authority of the state, but it also generates a dangerous contradiction for ruling classes: it arms and trains the very population that may later challenge its authority. During the Second World War the American bourgeoisie managed to maintain relatively strong ideological cohesion by presenting the conflict as a collective struggle against fascism. By contrast, the Vietnam War increasingly appeared as a colonial intervention fought for geopolitical advantage rather than a defense of society as a whole. As casualties mounted and living standards stagnated, class contradictions led to open opposition domestically and in the armed forces themselves. Thousands of incidents of desertion, refusal of orders, and “fragging” of officers revealed deep demoralization and class contradictions within the ranks. The experience convinced the American ruling class to abandon the mass draft army and replace it with the professional volunteer military that exists today.

Today the U.S. bourgeois are so arrogant and so decadent in their ways they make no effort at all to even justify their conflicts to the whole of society, but it is exactly this arrogance and false certainty of the final defeat of the proletariat, that will one day contribute to their downfall when the working masses awaken from their long slumber.

Capitalism Will Die & the Proletarian Will Be It’s Grave Digger

In the present context, the war in Iran must be understood as an expression of the deepening contradictions of global capitalism, rooted in overproduction, intensified competition, and the declining rate of profit. As the preceding analysis has shown, the struggle over oil, control of production, shipping chokepoints like the Strait of Hormuz, and access to Asian markets, has become central to inter-imperialist rivalry. The conflict reflects not simply geopolitical maneuvering but the attempt of competing capitalist powers to resolve economic stagnation through the violent redistribution of markets and resources. At the same time, the war unfolds against a backdrop of mounting sovereign debt among all the states of the world, with military expenditures generating profits for monopolies while forcing capitalist states to reduce funding for counter revolutionary social programs and increase its attacks on the working class, thus intensifying social contradictions which will inevitably lead to the mass resurgence of the global class struggle.

Historically, capitalism has sought to overcome crises through war, but this has always required enormous financial expansion. During World War II, the United States was able to sustain unprecedented levels of spending through massive debt accumulation, war bond campaigns, and state-directed economic mobilization, while the postwar order was stabilized through the creation of the Bretton Woods system, which reorganized global finance around the dollar and U.S. credit. This framework underpinned decades of expansion, allowing the international banking system to absorb and circulate growing levels of debt. Yet this very system now shows signs of exhaustion: the mechanisms that once enabled recovery have become sources of strain, as debt accumulates without corresponding productive growth and the financial architecture of global capitalism is increasingly stretched to its limits.

Today, the conditions that once made large-scale wartime expansion financially and materially viable have fundamentally eroded. During World War II, the United States was able to sustain an enormous war effort through a coordinated system of war bond sales, mass taxation, deficit spending, and direct monetary support from the Federal Reserve, all under conditions of full economic mobilization. War bonds alone financed roughly 40–50% of total costs, while measures like the Revenue Act of 1942 transformed income tax into a mass tax and pushed top marginal rates above 90%. Federal spending surged from about 10% of GDP in 1940 to over 40% by 1945, and total debt rose from roughly 40% to 120% of GDP. Crucially, this was made possible by specific historical conditions: unused industrial capacity from the Great Depression, a high domestic savings rate that could be redirected into state debt, strict rationing and price controls to suppress inflation, and a manufacturing base capable of rapidly converting civilian production into military output. The Bretton Woods system that followed institutionalized this model internationally, embedding U.S. financial dominance and enabling the global expansion of credit in the postwar period.

By contrast, contemporary states enter new conflicts from a far weaker position. The United States today already carries debt at or above 100% of GDP in peacetime, meaning a comparable wartime surge would push debt to unprecedented levels. The economy is highly debt leveraged across households, corporations, and government, leaving far less room for expansion through war bond borrowing. Unlike the WWII period, when total U.S. debt across households, corporations, and government was roughly around 100–120% of GDP, today it exceeds approximately 250–300% of GDP, meaning the entire economy is already highly leveraged and has far less capacity to sustain additional large-scale borrowing without risking financial instability.

As large portions of sovereign debt come due in the next few years, governments are being forced to refinance obligations that were originally issued under ultra-low interest rates at much higher current rates, dramatically increasing their cost of borrowing. According to recent global debt data, roughly 40–50% of sovereign debt in advanced and developing economies will mature by 2027, meaning trillions of dollars must be rolled over in a far more expensive financial environment. At the same time, many major economies are already running persistent deficits, so rising interest payments,now consuming tens or even hundreds of billions annually, are being financed through additional borrowing rather than revenue. This creates a compounding effect: governments are increasingly issuing new debt not to invest or stimulate growth, but simply to pay interest on existing obligations. As debt levels rise and refinancing costs increase, lenders begin to demand higher yields to compensate for perceived risk, further increasing borrowing costs. In turn, higher interest rates worsen fiscal balances, forcing even more borrowing. This feedback loop, often described as a “debt death spiral”,can reach a tipping point where credit markets begin to doubt a state’s ability to repay, making refinancing prohibitively expensive or unavailable altogether. At that stage, even advanced capitalist economies can face conditions historically associated with major systemic breakdowns rather than modern stability—conditions seen in earlier crises such as the post–World War I debt crises, the hyperinflation of Weimar Germany hyperinflation, or the widespread defaults and currency collapses of the Great Depression. In those periods, governments facing unsustainable debt burdens and rising borrowing costs were forced into sharp austerity, experienced rapid currency devaluation, or outright defaulted on their obligations. What was once considered characteristic of “less developed” or earlier capitalist phases,state bankruptcy, collapse of credit, and severe social dislocation re-emerges as a real possibility even for advanced economies when debt dynamics spiral beyond control.

At a deeper level, the turn toward war reflects the inability of capital to resolve its crisis through productive investment. Overcapacity in key sectors, including energy, and weak effective demand constrain profitable expansion, leading capital to seek alternative outlets in speculation, financialization, and ultimately militarism. The war in Iran, by disrupting production and raising prices, temporarily alleviates competitive pressures within the oil market, but it does so at the cost of further destabilizing the global economy. Rather than overcoming the contradictions of overproduction, war can work to intensify them in certain contexts, diverting resources into destruction while expanding the debt burden that weighs on future accumulation.

Finally, the social dimension of this crisis is already visible. The rising unrest among the Iranian proletariat prior to the outbreak of war serves as a canary in the coal mine of future proletarian defeatism. As economic pressures mount and states shift the costs of crisis onto the working class through austerity, inflation, and open repression, conditions are created for renewed waves of class struggle in the future. As Friedrich Engels presciently warned ahead of world war 1, “A world war… will lead to the bankruptcy of states and to such a general exhaustion that the conditions for the ultimate victory of the working class will be created.” The current trajectory of imperialist conflict—driven by overproduction yet financed through unsustainable debt—thus points not toward stabilization, but toward an escalating convergence of economic crisis and class confrontation on a global scale. The current wave of intensifying inter-imperialist war and rivalry will only be met with intensifying economic and social contradictions. Despite all of the bourgeois ever greater destructive powers, despite their ever growing totalitarian state apparatus they cannot escape the reality that ultimately capital sows the seeds of its destruction by forcing them at once to rearm the proletarian masses in open inter-imperialist warfare and simultaneously giving birth to greater class struggle as the world economies descend into chaos.
